The return of bloody conflict (3)
I believe the answer is:
war
'conflict' is the definition.
(war is a kind of conflict)
'the return of bloody' is the wordplay.
'the return of' shows that the letters should be reversed in order.
'bloody' becomes 'raw' (as in raw meat).
'raw' written backwards gives 'WAR'.
(Other definitions for war that I've seen before include "Open hostility" , "State of armed struggle" , "Fight" , "Armed hostility" , "Strife" .)
